ReasonML/BuckleScript
ReasonML在BuckleScript 的帮助下将 OCaml 编译为 JavaScript。通过安装依赖和创建bsconfig.json文件使用 ReasonML。
$ yarn add bs-platform --dev// bsconfig.json
// from https://github.com/BuckleScript/bucklescript/blob/master/jscomp/bsb/templates/basic-reason/bsconfig.json

ReasonReact 通过 ReasonML 构建 React。当然也能在 Parcel 中使用：
$ yarn add react react-dom reason-react// bsconfig.json
{

+ "react-jsx": 3

[@react.component]
let make = (~name) => {
<div> {React.string("Hello! " ++ name)} </div>;
};/* src/index.re */
ReactDOMRe.renderToElementWithId(<Greeting name="Parcel" />, "app");
